Am using Apache Solr 3.1.0 with Lucene 3.1.0. While indexing server got stopped due to hardware failure. I restarted my server but solr indexing is not happening.
am getting
SEVERE: java.lang.RuntimeException: org.apache.lucene.index.CorruptIndexExceptio n: document count mismatch: deleted docs count 0 vs segment doc count 148 segmen t=_otm
It seems to be a bug in below 3.6 versions reference. But how to upgrade to higher version with out losing the old indexes.
How to solve this. Any body can tell me.
Upgrading won't fix your problem.
Have a look at CheckIndex class. You can first run checkIndex() method (read-only) which would provide with the status information (CheckIndex.Status) and then you can run fixIndex(CheckIndex.Status status) in order to attempt to fix it. Good luck!
